Why does my phone act like it's plugged in all the time...

Just got my phone yesterday. Running Calk's 2.7 and ICS theme, set dpi to 160, looks and runs awesome. However, it always thinks it's either charging or plugged into USB. the red LED never wants to turn off. how can I remedy this problem?

Possibly try turning it off, booting to recovery, clearing cache/dalvik-cache, and then clear battery stats

Was it like this prior to rooting and custom rom?

Apk, that didn't do it.
yes, it did the same thing beforehand. Except takng out the battery solved the problem once.

Get it exchanged ASAP. This is a defect with the USB port. Has NOTHING to do with software. I was outside of my 14 day return and Sprint made me send it to Samsung to get fixed. $7 jig and two weeks later it was fixed.

With my tech background I would say check the charging port. Could be a metal shaving or *gasp* corrosion!

Shouldn't matter. The phone has a one year warranty from Samsung. I bought my wife an Epic on craigslist last year and had it repaired under warranty.

Yup. I had the same problem. I think it is related to the USB port (from reading a few SGS2 threads). I took it to the Sprint Store and they said the USB port looks good. They reset it and it still acted that way. However, 2 hours later the problem is gone. They ordered me a replacement so I'm still going to take it because who knows why the problem starts. I did have Calk's rom and also have the battering monitoring widget by 3C and I had cleared the battery stats multiple times prior to the symptoms starting. Just proving as many clues as possible...

What do you mean by reset?

Funny I see you have this problem (not really funny) because I noticed the same thing last night and just figured it was Rom related.

It sucks... can you give more details about the reset process? Soft reset?

no dice

I had the same problem.
The red light was on all the time, only went out when I got a text. If I pulled the battery the phone would show like it was charging as soon as I put it back in. It would show the battery animation on the screen not plugged in.
After a battery pull the phone would also not boot using the power button, had to boot to recovery and boot from there.
Took it to sprint, they gave me a new battery. Solved the problem only until phone was plugged in to charge. Then started all over again.
Turned out to be a problem with the USB port and they ordered me a replacement.

got it fixed! looks like the pcb on the port was sitting too close to the lower edge of the phone. pushed it up gently and now it seems to be working. thanks for the direction, nivron.
my other concern is that battery life sucks ass. drains really quick (at the rate of ~6%/hr!). again, running calk 2.7 + ics theme. also, taking out the battery seems to reduce the life 20%. what's the deal...

Hmm, now the USB cable needs to be at a certain angle for the phone to charge. Is there any way a Sprint store could furnish a replacement for me?

USB wont disconnect.

Hi I just got a e4gt used from a coworker for 80 bucks. But I'm having issues with it. Even off the cord, it says mtp connection. Every time I turn off the phone it sometimes starts right back up again on its own, and sometimes shows that it is charging, again while it is off the cord. Anyone have this problem? Since I got it used can I still take it to a sprint store and have them fix it? Thanks.
Its really annoying. I want to root it before I switch my service over since I want wifi tethering.

I have had this problem before. Once with my launch day e4gt and twice my current e4gt. The first one, I took to a corporate store and they replaced. The two times with this phone, I took a wooden tooth pick and cleaned the USB port (with the battery out). So far for me, that had remedied the problem.

Use another USB cable

I tried a different cable, same thing. Even when I connect a cable to the phone but not the computer, it thinks its connected. Starting to think I have a bad USB port or something. Since its used, do I have a manufacturers watlrranty or something?

If you have TEP, it would be free replacement at a sprint store. If you don't, it would be $35. We don't care about devices be used, per say.
However, this is all assuming there isn't corrosion in the charging port, which will generally cause the issues you are having. Take a peek in there with a small light and see if you can see any white cloudiness or rust.
Sent from my SPH-D710 using xda premium

What is TEP? Does the warranty carry over of im not the one who originally bought the device? The guy bought it in september i think.
Sent from my SPH-D710 using XDA

It sounds like liquid damage to me.
Look really closely inside your charging port for anything green/white, especially toward the very base of the pins. Also, look at the charger itself for any green/corrosion on the pins. If you find any, dip a toothbrush in some denatured alcohol and scrub your charging port.
Works like a charm.

Ok so after cleaning out the charger it seems to charge better, but it has a different problem too. It doesnt stay off. Every time i try to power down it automatically turns itself back on. I want to root this phone before i switch my service over. Is it safe to root this phone if it doesnt turn off and stay off? And would a coroded charger port be the cause of it turning itself back on?

Make sure the device is usable first. A corroded charging port could definitely help in bricking the device, by not completing a full flash during installation of software.

hi all,
n00b here so go easy !
im having similar issues to the OP, with the phone constantly telling me that charging has been paused , voltage too high , even when the phone is not charging.
my phone has just been returned to me from a warranty repair for a faulty button and camera , it took almost 2 months to have it repaired by samsung.
i really cant face not having my phone for another 2 months if it needs to go for repair again.
how much would it cost to have the usb replaced on the phone if i was to bring it to a standard phone shop ??
thanks in advance guys.
p.s. i wouldnt risk trying to D.I.Y. it as im really not good at that kinda stuff.

Are you activated on another carrier? Or do you not have TEP?

That's very odd. I've seen liquid damage cause the phone to stay powered on constantly, but normally doesn't have anything to do with the charging port.
Pull your battery and leave it out for a few hours to fully reset the internal battery and see if that does the trick.
Did you use Denatured or Isopropyl alcohol to clean out the port? If not, you may have damaged something.. It doesn't take a whole lot of alcohol to clean out the port, just a dip into the alcohol with a toothbrush and a lot of scrubbing.
Regarding this being a widespread issue, I don't know if the port is more susceptible to liquid, but I have seen this issue four times over the last month and a half.. (Mainly with the Galaxy Nexus) Cleaning the charging port has resolved it 100% of the time for me and I have not heard back from anyone saying the issue returned.

OK so for some reason the charging works and the phone is able to shut off. Now I have a new problem. My e4gt will charge when plugged into the pc, but the pc doesn't recognize it. I want to root my device, but the computer will not recognize it no matter what! I tried uninstalling the drivers, reformatting my phone / sd card, restarting the computer, reinstalling the drivers, and i just can't get the computer to see the phone. What can I do? This is driving me insane.

maybe try using odin and reinstall a stock el29 rom see if that helps in any way?

[Q] I need help with phone start and shut down loop

My T-989 has never been able to stay shut down if the charger is plugged in. I shut it off and don't plug in the charger it stays off. I shut it down and plug in, or plug in and shut down, either way, and it immediately it turns itself on. I knew the that this would be a problem somehow when I noticed it but, no one (no one as in thread replies to similar problem) seemed to think it was a problem. Well, I was using my phone as a hot spot for my laptop as I do pretty often and this time I ran the battery down to about 7% before I realized just how low it was. I had to finish what I was doing on the laptop before disconnecting the phone. As I finished and started to go into settings to turn off the hotspot option the phone shut itself off. I then plugged in the charger and the phone did it's little trick and turned itself on instantly. Being that it has no charge left in the battery, it shut itself down. And because it doesn't stay turned off when plugged in, it turns itself back on. So the cycle begins. It won't charge up because it keeps cycling. And it keeps cycling because it doesn't allow itself to sleep while plugged in. I need to somehow charge the battery outside of the phone I guess. But what about a fix for the never sleep bug? Do other Roms allow sleep while charging? How can I charge the battery other than the obvious of using another SII or wiring the battery contacts directly to a charger with the mini usb cut off? Will a charged battery solve the problem ? Or is it a soft brick and I need to Odin and flash a new Rom? How come nobody could foresee this "dog chasing its tail" scenario when the phones don't sleep when plugged in? I need to resolve this asap. And as I always do say, Thanks in advance for your help everyone on XDA.

Maybe hotpot app issue or bug. Do you think you could reflash without the app. Personally I've never have heard of anything like this but thats why this site is for. To help one another get the most out of our device.
I'm no dev not computer genius, and pls understand that what I'm giving is "my" opinion. I could be wrong or even maybe a chance to be right.
With that said, why not try to get the phone on cmw and do a darkside
Cache wipe and maybe that could help ur permissions. And maybe even fix ur prob, another idea was to wipe ur battery stats. Also on advance mode in cmw. It could be endless factors that have caused this issue. I know its not a lot of help but hopefully I'm pointing at he right road for u to fix your device

Thanks datrapstar. I first have to get the battery charged somehow. And even then the only thing I can do is USB jig into download. It stays in download when I remove the jig, but as soon as I connect a cable to it from the laptop or charger it starts the on off loop. So,????
Sent from my SAMSUNG-SGH-I897 using xda premium

And your doing the 3button combo? It should automatic start booting into download mode. I don't know exactly how to do the jig. You may wanna pm "all gamer" being that he's the one I seen posting about it, and ask him if he can give u a lil guidance.
Sent from my SGH-T989 using xda app-developers app

Also, are u capable of going into a retail tmo?, maybe they can let u charge up there on one of their display devices. Its at no cost to them. And sometimes u find one of the cool sales reps that is willing to go above and beyond. Its the best I good bro, sorry
Sent from my SGH-T989 using xda app-developers app

efforts that aren't in vain.
I'll start by letting you (datrapstar) know I appreciate your input. It is certainly welcomed . The jig I'm talking about is a plug - in (mini USB) device that jumps, or crosses two of the circuits of the female USB plug on your phone. It instantly puts your phone into download mode. Rather than the two or three button method, which in some instances won't work, the jig always ,99% of the time,works even if you have a unresponsive, almost bricked device. All that power for $10 plus shipping from MobileTechVideo,the guys who can modify your phone with the famous Unbrickable Modification. Okay, back to the issues at hand, my hand, to be exact.
I do have access to a TMo store, being that I live in " Lower Beverly Hills " we even have a valet parking lot across the way. I'm just fu##ing with ya Bro. But yeah, I may do just that to charge the battery. And I have a girl that works at one of the TMo retails that I use who has already gone above and beyond the call of duty for me that I may have to pay a visit to. I didn't have time to do anything today about my SGII, and fortunately I have my Captivate that I use as my business phone to keep me connected to everyone during this time of phone aggravation. I will keep posting with my progress toward a resolution, and I will gladly accept anymore input sent my way that might steer me towards a final solution. Oh, and sorry for the long, and wordy posts. (Not really) I like to write, and don't practice "textphonics" abbreviations or acronyms. Later Bro.

No doubt then ,hope it all works out for the best for u. I'll keep checking in on the tread and see how ur making out. And I'll also try doing a lil more research in any resolutions of the matter. Good luck:thumbup:

Cool. Talk again later.

Got it working
I got it working Thursday. The phone finally decided that it was gonna stay shut down and the battery recharged. I knew I could get it running after that. I probably did a few things that didn't need to be done but, I'm still new to this. I wiped everything (almost), Dalvick, Data, Battery, Cache, Factory Wipe and Reset. I probably forgot some. I Odin the .tar/md5 file and then rebooted. I just want to know how to fix the phone from not shutting off and staying off if the charger is plugged in, and which custom ROM I should try now ? I'm back to rooted, stock, Gingerbread 2.3.6 UVKL1, Baseband version UVLE1. Any ideas?

I'm on infamous 2.8 right now and I can't complain about it at all. 27+hrs battle life and thats with light use. As for the other issues the only thing I can think off it was just a bad download.

Have you tried plugging it into your computer? Does your computer recognize the phone if so? Do you get any LED indicators when plugged in?
I ask because I want to rule out a bad USB connector.

If you are doing data and processor heavy things, and potentially have screen brightness up, it will definitely toll on your battery anyway. Has this been an issue before? Or did it just start? Did it start with the installation of your current rom or some app? Need a little more info.
I would make a nandroid of your current ROM and restore back to TW stockish rom to see if anything improves (under the same circumstances). I am not in any way saying wicked is bad, but rather just helping rule out possibilities. While roms may work for most, there is always a chance that it does not work correctly on that one piece of hardware.

Might be something simple like a bad cable. Have you tried another charger and cable? I've had chargers and cables go bad and they did just what you described.

Faulty Battery Replacement

I have a SGSII E4GT and the battery just stopped charging. I have SlimBean Rom on and i was wondering if they will check any of that kinda of stuff or if they'll give me a new battery. There is no way to access the rom and all you see is the battery charging symbol so the only way anyone could know if i have a rom is if they turn the phone on.

Did you try different USB wires? It could be the port as well.
Sent from my SGH-I337 using xda premium

You could always buy 2 aftermarket batteries with an external charger for $20... Then you have spare batteries if you ever want/need them.
Then if the USB port is dead you can just flash a stock ROM.

How are you trying to charge the device? A wall charger or using usb on your pc? Depending on the kernel, usb charging via pc may be disabled by default in favor of some other service. You most likely will not receive a replacement battery unless you buy one yourself, in which case they arent even going to see your phone.
